Rapper Rick Ross and hot DJ/producer Marshmello are the latest additions to the Billboard Hot 100 Music Festival at Northwell Health at Jones Beach Theater on Aug. 19 and 20.

Organizers also announced plans Thursday for adding a fourth stage at the venue, the Emerging Artists Stage, featuring 14 up-and-coming artists from the tri-state area during the two-day festival. In its previous two years, the Billboard fest featured three stages — including one on the sands of Jones Beach, which will also be in place this year.
